BTTF Week: 'Back to the Future 1 & II' Comparison

Have you ever watched the ending of Back to the Future and the beginning of Back to the Future II side-by-side? Fans of the series are already well aware that the original Jennifer (Marty's girlfriend) played by Claudia Wells was replaced by Elisabeth Shue for the sequels, thus making it so filmmakers has to re-shoot the ending of Back to the Future with the new Jennifer at the start of Back to the Future II. But how close did they get it? Did any of the lines change? What about facial expressions and body movements? Only the hardcore BTTF geeks (like me) will probably dig this, but I thought it was fairly interesting to watch both scenes next to one another.

Check it out after the jump and let us know if you pick anything up. My favorite part comes in at around the 1:46 mark ...
